PowerProtect Linux 文件系统注册失败，并显示“首选地址无效”

PowerProtect Data Manager 用于通过文件系统代理（应用程序代理）保护 Linux 服务器。使用完全限定域名 （FQDN） 或 IP 的应用程序代理注册失败，并显示“首选地址无效”。

[root@my-application-agent]# /opt/dpsapps/agentsvc/register.sh --enable
AgentService is already commissioned.
Enter the PowerProtect Data Manager server FQDN or IP address: my-ppdm.my-domain.com
The PowerProtect Data Manager server FQDN or IP address that is used by the application agent host is my-ppdm.my-domain.com
To use the Fully Qualified Domain Name (FQDN) as the preferred address for the agent host, in the PowerProtect Data Manager UI, go to Infrastructure > Application Agents and select Configure DNS Name Resolution.
Enter the preferred FQDN or IP address of the application host: my-application-agent.my-domain.com
preferred address is invalid
Enter the preferred FQDN or IP address of the application host: XXX.XXX.XXX.XXX
preferred address is invalid
Failed to get a valid preferred address of the application host even after 2 attempts. Failing registration

应用程序代理和 PowerProtect Data Manager 之间的名称解析正常工作。PowerProtect Data Manager Application Agents 页面显示使用应用程序代理 IP 地址和 localhost.localdomain进行的注册。

应用程序代理 /etc/hosts 文件包含 localhost.localdomain 的 127.0.0.1 环回条目。localhost.localdomain 导致应用程序代理配置在注册期间使用不正确的名称。

[root@my-application-agent]# cat /etc/hosts
127.0.0.1	localhost.localdomain locoalhost
::1		localhost.localdomain locoalhost
XXX.XXX.XXX.XXX my-application-agent.my-domain.com my-application-agent

应用程序代理 /etc/hosts 应注释或更新 localhost.localdomain 的文件行，以反映应用程序代理名称。

[root@my-application-agent]# cat /etc/hosts
#127.0.0.1	localhost.localdomain locoalhost
#::1		localhost.localdomain locoalhost
XXX.XXX.XXX.XXX my-application-agent.my-domain.com my-application-agent

或

[root@my-application-agent]# cat /etc/hosts
XXX.XXX.XXX.XXX my-application-agent.my-domain.com my-application-agent
127.0.0.1	my-application-agent.my-domain.com my-application-agent
::1		my-application-agent.my-domain.com my-application-agent
